R1 Flashcards
- Renal artery stenosis is common in?
- Patient with diffuse atherosclerosis
- First-line treatment in case of RAS induced HTN
- ACE inhibitor (safe in unilateral (just follow RFT) and bilateral until CR raise less than 30%)
- Mechanism
- Inhibit the RAAS which cause the HTN in RAS
. Why is RAAS activated in case of RAS
- (to maintain GFR by constricting efferent arteriole)
- Benefit
- Reduce HTN, decrease the risk of Ce. V and Ca. V complication
- Other additional Tx
- Treat DM, Additional antihypertensive for control of B/P, Tx hyperlipidemia and smoking section
1.When to consider Surgical revascularization and stunting
- Failure of medical therapy, recurrent flash pulmonary edema, and CHF secondary to HTN
- Why we didnt consider as primary therapy
- No outcome d/c with that of medical therapy
- Symptom and sign of salicylate toxicity
- Tinnitus, fever and tachypnea
- Acid base disturbance?
- Respiratory alkalosis(stimulate respiratory center) with metabolic acidosis(decoupling of oxidative phosphorylation)—Near normal PH, Low pco2 and low HCO3
How we asses presence of Respiratory alkalosis in presence of Metabolic acidosis?
Use winter formula to asses expected Paco2 level?
winter formula?
PaCO2=1.5xHCO3 + 8 +-2
if PaCO2< expecter suspect concomitant respiratory alkalosis
How to asses concomitant respiratory acidosis in case of metabolic alkalosis?
Change in PaCO2=0.7 x change in HCO3(assuming the Normal HCO3 is 24)
Took the normal CO2 range of 33-45
metabolic acidosis classification?
normal anion gap(8-12)
high anion gap(>12)
anion gap calculation?
Na -(Cl + Hco3)
High anion gap cause?
GOLDMARK Glycol(ethylene and proline) Oxopeoline(a metabolite of acetaminophen) Lactic Acidosis D-Lactate(exogenous) M-methanol and other alcohol Asprin Renal failure Ketone
Normal AGMA?
HARDASS Hyperlimation(hypochloremia) Addison disease Renal tubular acidosis Diharoa Acetazolamide Saline infusion Spironolactone
Menifestation of diuretic abuse?
hypovolemia Hyponatremia Hypokalemia Hopoclorimia But will have high urinary Na, K but vary CL
A disease that causes high urine NA despite hyponnatremia?
Diuretics
Adrenal insufficiency
Cerebral salt wasting syndrome
Disease that cause high urine K level despite hypokalimia?
Diuretics
Primary adrenal insuficiency
Renal tubular acidosis
cause of hypochloremia?
Diuretics
Contraction alkalosis
In both cases, the urine concentration can vary
the factor that causes hypokalemia, alkalosis, and normotension?
1-sever vomiting
2-Diuretics abuse
3-Gitelman’s syndrome
4-Bartter syndrome
1-serpitious vomiting evidence ?
scar/callus in dorsum of hand
dental erosion
hypochlorimia and low urine CL
2-Diuretics abuse, Gitelmans syndrome
and Bartter syndrome?
High urine CL level
What about primary primary hyperaldostronism?
Hypokalemia.Metabolic alkalosis but have HTN
Bartter syndrome?
Reabsorption defect in thick ascending loop of Henle (affects Na+/K+/2Cl– cotransporter) Metabolic alkalosis, hypokalemia, hypercalciuria Autosomal recessive Presents similarly to chronic loopdiuretic usage
Gitelman syndrome?
Reabsorption defect of NaCl in DCT Metabolic alkalosis, hypomagnesemia, hypokalemia, hypocalciuria Autosomal recessive Presents similarly to lifelong thiazide diuretic use Less severe than Bartter syndrome
How to d/t barrtner from gitelman?
B-Hypercaceiuria
G-Hypocalciuria
Hepatorenal syndrome manifestation?
End-stage liver disease
w/o clear cause identified
minimal haematuria
lack of improvement with resuscitation
pathophysiology?
difiuse pheripherial vasodilation mainley splancnic—RAAS activation==Renal hypoperfusion—decrease renal perfusion and low GFR–AKI
managment?
Liver transplantatioin candidate
stop liver injuring practice

Common initiating factor?
upper GI bleeding
